List of sumo tournament winners
From Wikipedia, the free encyclopedia
This is a list of sumo wrestlers (or rikishi) who have won the top Makuuchi division championship (or yusho) since the introduction of six honbasho, or main tournaments, per year in 1958.
The championship is determined by the wrestler with the highest win-loss score after fifteen bouts, held at a rate of one per day over the duration of the 15 day tournament. In the event of a tie a play-off is held between the wrestlers concerned.
Names in italics mark an undefeated victory (a zensho-yusho).
